Behavior of high-pressure CH4/CO2 reforming reaction over mesoporous Pt/ZrO2 catalyst

► Mesoporous Pt/ZrO2 catalyst was prepared by combining sol-gel and templating methods. ► H2 formation activity over the catalyst at 1.0 MPa was higher than non-porous Pt/ZrO2. ► At a GHSV of 60,000 h−1 at 1.0 MPa, H2 space-time yield reached 93 mmol/h/gcat.
